    ip neigh add can do this:

    For example:

    root@refactor:~# ip neigh show
192.168.1.1 dev wlan0 lladdr 00:1b:da:29:3a:87 REACHABLE
root@refactor:~# ip neigh add 192.168.1.2 dev wlan0 lladdr 00:1b:da:29:3a:89
root@refactor:~# ip neigh show
192.168.1.2 dev wlan0 lladdr 00:1b:da:29:3a:89 PERMANENT
192.168.1.1 dev wlan0 lladdr 00:1b:da:29:3a:87 REACHABLE

    Is this what you want to do?

    If you want to do this directly in C, look at the source of the ip tool, which is part of the iproute2 package.
